Description

Technical Field

[0001] The utility model belongs to the technical field of charger aging test, and particularly relates to an aging tool for testing chargers. Background Art

[0002] A charger is a common charging device. It adopts high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology, and has the characteristics of high charging efficiency, simple operation, light weight, small volume, etc. To ensure that the output products have good functions, all products need to be subjected to aging tests when leaving the factory. The aging test project refers to the process of strengthening the test under corresponding conditions for the aging of the charger caused by various factors involved in the actual use conditions of the charger.

[0003] When testing the aging of existing chargers, generally the charger is placed beside the aging tool, and the wires connecting the charger to the aging tool are distributed around the device. During the aging test, when the staff moves around, it is easy to drag the wires, resulting in wire detachment, affecting the aging test effect. In addition, the internal structure of the existing aging tool is complex, and the electrical equipment is arranged alternately, resulting in poor heat dissipation effect, which in turn affects the test effect and service life of the aging work. Therefore, we propose an aging tool for testing chargers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an aging tool for testing chargers to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An aging tool for testing chargers, including an installation bracket and a housing, and the housing is installed on the installation bracket. A DC charging gun seat is arranged on the left side of the front of the housing, and a DC charging gun is inserted into the front end of the DC charging gun seat. A communication circuit board is arranged on the inner wall of the front end of the housing. Enclosures are arranged on both the left and right sides of the upper surface of the housing. An upper protective cover is sleeved on the outer surface of the charger, and the inner wall of the lower end of the upper protective cover abuts against the outer walls of the two enclosures. A charger is placed between the two enclosures. A load resistor is arranged on the right side of the inner bottom of the housing.

[0006] Preferably, a cooling fan is arranged on the right side of the load resistor, and the cooling fan is fixed to the right inner wall of the housing by bolts. Ventilation holes are arranged on both the left and right sides of the housing.

[0007] Preferably, a transparent panel is arranged on the rear side wall of the housing, and a power-on connector is arranged at the lower left end of the transparent panel.

[0008] Preferably, a digital tube and a switch are arranged on the right side of the front of the housing, and a signal lamp is arranged below the digital tube.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The test charger uses an old chemical equipment. Through the provision of enclosures and upper protective covers, the charger can be placed on the upper surface of the outer shell and fixed in a limited position. The charger does not need to be connected to the old chemical equipment through a long wire, which avoids the phenomenon of workers dragging the wires when walking, thereby improving the effect of the aging test.

[0011] (2) The test charger is equipped with an old chemical device. Through the cooling fan arranged next to the load resistor and the ventilation holes opened on the left and right sides of the outer shell, the cooling fan can quickly discharge the heat inside the outer shell to the outside when the old chemical device is tested, avoiding the internal temperature of the outer shell from being too high and affecting the working effect of the load resistor or damaging the load resistor, thereby improving the use effect and service life of the aging work.

When the device is not in use, the DC charging gun 5 can be unplugged from the DC charging gun seat 11 first, and then the front end of the DC charging gun seat 11 can be sealed by the sealing cover to prevent external dust and moisture from entering the inside of the DC charging gun seat 11, polluting and corroding the DC charging gun seat 11, thereby improving the service life of the DC charging gun seat 11.

[0018] The DC charging gun seat 11 is fixed on the outer housing 2 by M6 round head screws. A digital tube 12 and a switch 13 are arranged on the right side of the front surface of the outer housing 2. The digital tube 12 is provided to display the current and voltage passing through during the operation of the device. The switch 13 facilitates the staff to turn on and off this aging tooling through the switch 13, and the switch 13 is fixedly installed on the outer housing 2 through a threaded nut.

[0020] On both the left and right sides of the upper surface of the outer housing 2, there are enclosures 10 provided. An electric charger 4 is placed between the two enclosures 10. The provision of the enclosures 10 enables the electric charger 4 to be limited in position when placed on the upper surface of the outer housing 2, preventing the electric charger 4 from slipping off the upper surface of the outer housing 2 and making the electric charger 4 more stable during aging. Moreover, the enclosures 10 are of U-shaped design and only limit the left and right sides of the electric charger 4. Ventilation holes are provided below the front and rear ends of the electric charger 4, facilitating the discharge of the heat inside the electric charger 4 through the ventilation holes opened at the front and rear ends of the electric charger 4 when the electric charger 4 is working, avoiding damage to the electric charger 4 due to excessive internal temperature. A upper protective cover 3 is sleeved on the outer surface of the electric charger 4, and the inner wall of the lower end of the upper protective cover 3 abuts against the outer walls of the two enclosures 10.

The provision of the ventilation holes 8 enables the external air to circulate with the air inside the outer housing 2, facilitating the rapid discharge of the heat generated during the operation inside the outer housing 2 and avoiding damage to the load resistor 14 or affecting the operation quality of the load resistor 14 due to excessive internal temperature of the outer housing 2.

[0021] The working principle and usage process of the present utility model: When performing an aging test on the electric charger 4, first place the electric charger 4 on the upper surface of the outer housing 2, and limit and fix the electric charger 4 above the outer housing 2 through the two enclosures 10 above the outer housing 2. Then, cover the upper protective cover 3 on the electric charger 4 to further limit and protect the electric charger 4, avoiding the influence of external factors on the electric charger 4 during the aging operation. Then, insert the DC charging gun 5 installed on the electric charger 4 into the DC charging gun seat 11, and then connect the power cord of the electric charger to an external power source and start the switch 13, enabling the aging tooling to perform an aging test on the electric charger 4. During the working process, the cooling fan 7 works synchronously to discharge the heat inside the outer housing 2 to the outside through the ventilation holes 8, avoiding excessive internal temperature of the outer housing 2 from affecting the working quality of the aging tooling. The current and voltage during the test by the aging tooling can be understood through the digital tube 12, so that the staff can adjust and understand the aging state of the electric charger 4 at any time, realizing the aging test of the electric charger 4.
